Talk to your doctor before trying this technique if you have a heart rhythm problem, also known as an arrhythmia.
When is Valsalva maneuver contraindicated?
Valsalva manoeuvres are contraindicated in patients with SVT associated with: acute myocardial infarction • haemodynamic instability (eg systolic blood pressure <90 mmHg) • aortic stenosis • carotid artery stenosis • glaucoma or retinopathy.
What does the Valsalva maneuver do to heart rate?
The Valsalva maneuver reduces cardiac output, which is the amount of blood that the heart puts out with every beat. The individual may feel lightheaded or dizzy as a result. Once the baroreceptor senses the decrease in heart rate and blood pressure, it will stimulate the sympathetic nervous system.

Why does the Valsalva maneuver work?
The Valsalva maneuver is a breathing method that may slow your heart when it’s beating too fast. To do it, you breathe out strongly through your mouth while holding your nose tightly closed. This creates a forceful strain that can trigger your heart to react and go back into normal rhythm.

However, the conversion of AF to sinus rhythm is usually not associated with vagal manuvers. Thus, AF is classically treated with medication and electrical cardioversion.
What does the Valsalva maneuver test for?

Does the Valsalva maneuver increase heart rate?
HEART RATE RESPONSE TO VALSALVA MANEUVER 21‐5). Phase 1 consists of a transient rise in arterial pressure and an associated decrease in heart rate. In phase 2, the expiratory phase of the maneuver, there is a gradual decrease in blood pressure followed by a recovery. An increase in heart rate accompanies this phase.
When should you not do vagal maneuvers?
Carotid Sinus Massage – Avoid carotid sinus massage (CSM) in patients with carotid bruits and patients with a history of transient ischemic attack (TIA) or stroke. Also, avoid it in patients who have experienced ventricular tachycardia, ventricular fibrillation, or myocardial infarction in the past three months.
What are the risks of the Valsalva maneuver?
